To all whom it 12tay c onoern Be it known that L l lonajon BQHj t T a citizen of the llnited Stateai'emding at Indianapolis, h iarioncounty, andState of .1 idiana', have invented and rdiscovere'dcer- 'Shapedyoffwhich-the following is a spec'iandfitsyobjects are to provideja device of thisclassf hav ng means for preventing the rupture of the fibersot the wood by the compressive tensile strains applied thereto while the wood is being'bent into shape and to pro vi de, means whereby the article. after being sobent while held'inthefjacketpmay be immediatelyforced into a form where it shall acquirethe desired permanent set in the shape into which itjhas been bent while in the jacket, thus enabling a's'ingle jacket to be employed for "the; preliminary shaping for an desired number woody bending operations and in connectionfwlth a multiplicity o l-"forms or shape retainers.

With these objects in. view, my inilrention is embodied in preferable form in thedevlce hereinafter described and illustrated in the accompanying drawings. I I In these drawings, Figurel 1s a plan view of the device showingapiece OI wood in place thereiniand showing such' device and wood in fulllines before the wood has been bent to its desiredshape and showing the device and'woodindotted linesafter is a detail vertical section on the line 8-3 of Fig. 1 and Fig. dis a detail section on areverse curve. This bending Wlll impart line l-Jlof Fig.1. y p I Referring to the drawings, 11s the Wooden article, such as a snath. The woodin a ph able condition is inserted into thejacket." This acket comprises end members .2; 3,

which are adapted to respectively press against the oppositeextremitiesof the wood. The particular end member "lllelll shown Specificationof Patent.

5 article with a View to preventing elongation of the latter.

. 'l hom one side of each end member eX- tends a pliable non-extens1ble strap 5 preferably of "metal which may be fastened at one end tothe end member in any suitable thedrawings and it consists of looping the end ofthe strap around the stem 8 of a cylindrical stud of the yoke member which stud may be integral with or structurally separatefrom the body of the yoke member,

the free end of the strap being carried back upon'itself 'and'the over-lapping portions r veted together. l

bridge 9 connects the cylindrical stud 8 with a similarstud member 10. Formed position in the jacket or strap.

The outer stud members 10 are connected by means of a rigid non-extensible pliable "strap12, preferably of metal which extends along the. outer side of the article at the central part of the latter. It will thus be seen that when the article is placed in the jacket, it is held'within a retainer which is nonextensible longitudinallybut which is pliable transversely of its length. After the wooden article has been thus placed in the acket it is bent to the form indicated by dotted lines which action may be effected by any suitable means, such as a plunger forced The effect of this action is to bend the article on a, compressing action to the fibers on the inner side of such curve and a tensile strain on the fibers on the outer face of the curve I} p Patented Aug. 3,1915; Application filed ('lc-tober e, leis. sena1no;7e3,5s4.

the fibers to be ruptured and to separate, Y

, members with respectto the yoke members the jacket accommodates itself to the shape of the, article as the latter is bent and the rupture of the fibersisavoidednotbnly by c the prevention of elongation but also by the pressure of the straps at the peaks of curvature. As soon as'the art cle has been-thus bent into'the desired form,.1t is forced 1m:

mediately from the jacket into asuitable form of the usual construction and in Which the article is retained until it has stiffened into permanent form. The remoyalof the article from the jacket is enabled to be effected by means ofthe open yoke 11 andthe open endblocks. After an article hasbeen thus bent and forced into a form the acket may be immediately utilized for holding and protecting another article and theoperation erations. i
